Detailed Description
The technical solutions of the present invention are further described in detail with reference to the drawings and specific embodiments, which are only illustrative and not intended to limit the present invention.
As shown in fig. 1, a low-temperature fuel reforming device comprises an oil supply subsystem, an engine 6, an external reformer 3 coupled with exhaust gas, a sensing subsystem and a control subsystem.
The oil supply subsystem comprises an oil tank, a fuel pump 1 and a nozzle 2 which are connected in sequence; the external reformer 3 is arranged outside the engine 6, the external reformer 3 is provided with two air inlets and an air outlet, the air outlet is connected with one end of a reformer exhaust passage 41, and the other end of the reformer exhaust passage 41 is communicated with an engine air inlet pipe 5 and is used for premixing reformed air and air in the engine air inlet pipe and then enabling the premixed reformed air to enter a main combustion chamber; the first air inlet is communicated with the nozzle 2 and is used for injecting fuel into the external reformer 3, the second air inlet is connected with an engine exhaust passage 42 and is used for injecting at least part of exhaust gas discharged by an engine into the external reformer 3 to be mixed with the fuel injected by the nozzle 2 and be reformed, wherein the fuel is mainly reformed with oxygen in the air in the exhaust gas, and water vapor in the exhaust gas contains larger heat and is mainly used for accelerating reforming reaction. The reformed mixture passes through the reformer exhaust 41 into the engine intake. And the engine exhaust passage 42 is also provided with an exhaust gas control valve 7, the exhaust gas control valve 7 is a three-way control valve, two end parts of the exhaust gas control valve 7 are respectively connected with the engine exhaust passage 42, and the other end part of the exhaust gas control valve is connected with an exhaust gas branch pipe 8 and used for regulating and controlling the flow of the exhaust gas in the engine exhaust passage 42 flowing to the external reformer 3 according to requirements.
The sensing subsystem comprises a temperature sensor and a pressure sensor which are arranged on the engine cylinder cover and used for measuring the temperature and the pressure of the engine cylinder cover and sending the temperature and the pressure to the control subsystem.
And the control subsystem is used for regulating and controlling the waste gas control valve 7 according to the temperature and pressure values of the engine obtained by the sensing subsystem, and regulating the waste gas entering the external reformer 3, so that the activity of the reformed gas is regulated.
The reforming loop of the low-temperature fuel reforming device runs (the valve is fully opened):
the fuel pump 1 sucks fuel out of a fuel tank and sprays the fuel into an external reformer 3 through a nozzle 2; meanwhile, after being discharged through the engine exhaust passage 42, the engine exhaust gas is regulated and controlled by the exhaust gas control valve 7, one part of the engine exhaust gas enters the external reformer 3, and the other part of the engine exhaust gas is discharged through the exhaust gas branch pipe 8. In the external reformer 3, the fuel absorbs the waste heat of the exhaust gas, and reacts with the remaining air in the exhaust gas to reform the exhaust gas. The reformed gas enters the engine air inlet 5 after passing through the reformer exhaust passage 41, enters the engine main combustion chamber along with air, and is mixed and combusted with fuel oil sprayed by the engine fuel injector 9.
As shown in fig. 2, a specific reforming gas control method is as follows:
a temperature sensor and a pressure sensor which are arranged on a cylinder cover of the engine respectively detect the temperature and the pressure of the engine;
setting 2 reformer chamber temperature limits, which in order from low to high are a first temperature limit of 500K and a second temperature limit of 1800K;
in the engine starting stage, no waste gas exists in the external reformer, and fuel directly flows into an engine air inlet passage 5 through the external reformer 3;
when the temperature of the engine is lower than the first temperature limit of the preset reforming chamber of 500K and the pressure of the engine is lower than the preset pressure of 8MPa, the combustion in the cylinder of the engine is insufficient, the control subsystem controls the waste gas control valve 7 to send 5% of waste gas into the external reformer 3, and the rest is discharged through the waste gas branch pipe 8. At the moment, the external reformer 3 has the advantages of low waste gas content, less oxygen, low fuel reforming degree, high activity, full in-cylinder combustion promotion and optimized combustion.
When the temperature of the engine is higher than a preset first temperature limit 500K of the reforming chamber and lower than a preset second temperature limit 1800K, and the pressure of the engine is higher than 8MPa and lower than 20MPa, the engine cylinder normally works at the moment, the control subsystem controls the waste gas control valve 7 to send 6-14% of waste gas into the external reformer 3, and the rest is discharged through the waste gas branch pipe 8.
When the temperature of the engine is higher than the preset second temperature limit 1800K of the reforming chamber and the pressure of the engine is higher than the preset pressure of 20MPa, the combustion in the cylinder of the engine is violent; the control subsystem controls the waste gas control valve 7 to send 15% of waste gas into the external reformer 3, and the rest is discharged through a waste gas branch pipe 8. At this time, the external reformer 3 has a large content of exhaust gas, a high temperature, a high fuel reforming degree, a low reforming activity, and suppresses combustion to control combustion products.
The exhaust gas intake strategy is judged by monitoring signals of a temperature sensor and a pressure sensor of the engine, generally, the fuel injection quantity is communicated with the signals of the sensor, the fuel injection quantity is less at low load, namely, the corresponding temperature is less than 500K, the pressure is less than 8MPa, the quantity of the exhaust gas entering a reformer is reduced, the reforming degree of the exhaust gas is reduced, the activity of reformed gas is improved, and the combustion in the engine is more sufficient; the fuel injection amount is moderate during medium load, and the air input of the reformer waste gas is flexibly adjusted according to the sensor so as to meet the combustion requirement; the fuel injection amount is larger at high load, at this time, the amount of the waste gas entering the reformer is increased, so that more part of the fuel is oxidized in the reformer, the activity is reduced, and the fuel enters the engine to control the in-cylinder combustion.
The invention controls the exhaust gas of the engine to directly enter the reformer according to the temperature and the pressure of the engine and utilizes the waste heat, the air and the moisture in the exhaust gas to reform the fuel, thereby omitting a heat exchanger of the prior external reformer and correspondingly omitting a heat exchange process in the control method.
In summary, the present invention proposes a reforming system using an external reformer to generate low-temperature reformate in different oxidation stages according to the actual operating conditions of the engine, and the reforming system does not add a catalyst. The difference between the present invention and other corresponding fuel reforming technical schemes is that 1, the external reformer is directly linked with the exhaust gas of the engine, and the waste heat and the residual air are fully utilized; 2. by controlling the amount of the waste gas entering the reformer, a plurality of reformed products are obtained, so that an efficient clean combustion mode with layered control of activity and concentration is realized by only adopting a single fuel, and the adjustable control of a combustion reaction path is realized.
Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and those skilled in the art can make many modifications without departing from the spirit and scope of the present invention as defined in the appended claims.
